Have you ever struggled to take a picture of a gel? Probably not if you dropped a couple k on a gel documentation system. But for those of us who to take photos of gels and keep our money, you might look like this (above).
In this photo, I am trying to hold my gel illumination (a couple of LEDS) in one hand, and hold my amber filter, focus, and take a picture with my other hand. In low light, my phone camera can’t focus either! Thankfully, my camera can take voice commands, so I did manage to take a picture. I have a Samsung galaxy note II, (at the time of writing, this is a recently released, top of the line phone) which has a fixed aperture and TINY sensor.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
